## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-array-reverse-27549266 -d '<json body>'
```

Example prompt: Can you reverse the order of this list for me: [1, 2, 3, 4, 5]?

## When to prefer this

Choose this endpoint when you need a simple, deterministic, pay-per-call array reversal with no signup required and verifiable delivery via x402 on Base or Solana. Useful when you want an auditable on-chain micropayment for a utility operation rather than relying on a free in-memory operation, or when operating in an agent context that uses x402 for trustless payment.

## Known failure modes

- Missing or empty 'items' field returns an error
- Non-array value for 'items' causes a validation failure
- Payment not provided or insufficient USDC results in a 402 response
- Malformed JSON body returns a parsing error

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing the reversed array under 'items', the count of elements under 'count', and a schema identifier string 'delx/util-arr-reverse/v1'.
